If you're looking for the best mattress on the market, you won't be disappointed with Cocoon by Sealy. Its Chill mattress line has been voted one of the best budget options for hot sleepers and one of the best choices for stomach sleepers. The Chill mattresses are notable for their ability to absorb and dissipate heat and provide a refreshing sleep.

Chill mattresses come in two types: medium soft and extra firm. Medium Soft offers more cushioning (ideal for side and multi-faceted sleepers), while Extra Firm is more firm and supportive (ideal for back sleepers). Cocoon by Sealy offers free return shipping if you are not sure which mattress is right for you. All mattresses also come with a 10-year warranty.
